This is the hose that connects the outlet side of the filter-drier mounted beside the condenser in front of the radiator support to the expansion valve mounted near the firewall. NOTE - The filter-drier was mounted on 1967-68 models either in front of the radiator support or on the front of the passenger-side fender-well. This hose only fits models with the filter-drier mounted in front of the radiator support.

CONVERTING GENERAL MOTORS CARS

TO 134a

Until 1995, most cars with air conditioning used R-12 Freon refrigerant that is said to have a negative side effect of damaging the ozone layer and is no longer produced in most countries. since then, the industry standard has been R134a, which is an efficient replacement. Contrary to popular belief, most cars originally equipped with R-12 can be converted to 134a and still keep you just as cool.

Insure that the system is clean and free of contaminants (Depending on component condition, this may be a simple matter of blowing out with compressed air or liquid flushing with an air-conditioning flushing agent)

Replace or restore all rubber hoses with barrier hose.

Rebuild hot gas valve.

Install 134a charge port adapters.

Charge with 134a between 70-80% of the original R12 charge amount. Note: Hot gas valve will need to be adjusted during the charging process to properly adjust the low side by-pass pressure to 20psi.

Replace any o-rings with 134a compatible.

Recommended:

Install hi/lo pressure switch

HELPFUL HINTS

Ignore the sight-glass. A properly charged 134a system will likely show bubbles in the sight-glass.

Typical 134a charge rate will be approximately 70-80% of the factory R12 charge amount.

Insure that the system is clean and free of contaminants (Depending on component condition, this may be a simple matter of blowing out with compressed air or liquid flushing with an air-conditioning flushing agent)

Replace or restore all rubber hoses with barrier hose.

Rebuild suction throttling valve.

Install 134a charge port adapters.

Charge with 134a between 70-80% of the original R12 charge amount. Note: Suction throttling valve will need to be adjusted during the charging process to properly adjust the low side by-pass pressure to 20psi.

Replace or restore all rubber hoses with barrier hose.

Install 134a charge port adapters.

Have POA valve recalibrated/rebuilt for 134a, or replaced with a POA Delete Kit
